| /** |
| * <p> |
| * An instance of <code>ICommand</code> is a handle representing a command as |
| * defined by the extension point <code>org.eclipse.ui.commands</code>. The |
| * identifier of the handle is identifier of the command being represented. |
| * </p> |
| * <p> |
| * An instance of <code>ICommand</code> can be obtained from an instance of |
| * <code>ICommandManager</code> for any identifier, whether or not a command |
| * with that identifier defined in the plugin registry. |
| * </p> |
| * <p> |
| * The handle-based nature of this API allows it to work well with runtime |
| * plugin activation and deactivation. If a command is defined, that means that |
| * its corresponding plug-in is active. If the plug-in is then deactivated, the |
| * command will still exist but it will be undefined. An attempts to use an |
| * undefined command will result in a <code>NotDefinedException</code> being |
| * thrown. |
| * </p> |
| * <p> |
| * This interface is not intended to be extended or implemented by clients. |
